Client-side encryption
Encrypting data before sending it to the cloud provider
Short definition
Encryption performed on the customer’s device or within its environment before data is sent to the cloud provider. Its effectiveness in limiting provider access depends on control of the keys and the software used. Metadata and some search or collaboration functions need separate assessment.
